3M 7100178275 Quick Change Fibre Disc 36 Grit 4.5 Inch

Product Description

The 3M 7100178275 is a quick-change coated fibre disc designed for aggressive material removal on hard-to-grind metals, including stainless steel and high nickel alloys. Built around 3M Precision Shaped Grain, the disc delivers higher cut rates and a cooler cutting action compared to conventional fibre discs. A grinding aid is integrated into the construction to minimize heat buildup, making it a reliable choice for heat-sensitive alloys. The stiff fibre backing and strong resin bond contribute to tear resistance and extended disc life. It is sized at 4.5 inches in diameter and rated at 36 grit for heavy stock removal.

This disc is intended for professional metalworking applications including weld removal, blending, beveling, edge chamfering, and finish refinement. It is well suited for fabrication shops, maintenance facilities, and field service environments where stainless steel and high nickel alloy work is routine. The quick-change attachment system allows for fast disc swaps, reducing downtime during production grinding. Compatible disc pad face plates and hubs are sold separately.

Key Features

• Stiff fibre backing and strong resin bond provide durability and tear resistance under heavy use
• Quick-change design allows fast disc replacement without additional tooling
• 36 grit coarse abrasive rated for weld grinding, beveling, and edge chamfering
• Long disc life helps lower cost per part in high-volume grinding applications

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on stainless steel and high nickel alloys in weld removal, blending, and finish refinement applications.

Installation Notes

This disc should be mounted by a qualified operator following the grinder and disc pad manufacturer's instructions. Inspect the disc for damage before each use and never operate above the rated speed for the disc or grinder. Ensure all workpiece fixtures are secure and appropriate personal protective equipment, including face shield and gloves, is worn during operation. Disc pad face plates and hubs are required and sold separately.
